Function useQuery

useQuery<
    T = unknown,
    H = InstanceHeaders,
    P = InstanceParams,
    S = InstanceState,
    RH = InstanceResponseHeaders,
    E extends Record<string, any> = any,
>(
    engine: FetchEngine<H, P, S, RH>,
    path: string,
    options?: QueryOptions<H, P, E>,
    observer?: ObserverEngine<E>,
): QueryResult<T>
Apollo-style query hook — auto-fetches on mount, re-fetches when reactive config changes. Returns { data, loading, error, refetch, cancel }.

data is the parsed response body (not the full FetchResponse).
```
const { data, loading, error } = useQuery<User[]>(api, '/users', {
    reactive: { params: { page: 1 } },
});
```
